Skip Soho and its overpriced feta salads. One of London's most interesting eating corners sits along Harrow Road in Westminster, a ward of around 11,500 people that ranks in the top one per cent for ethnic diversity in Britain and is the most densely populated in the country. Writer Queenie Shaikh spent 24 hours there and counted over ten different cultures within a single mile.

The food alone justifies the trip. Tsiakkos is a Greek Cypriot restaurant so low-key there's no sign outside – diners perch at tiny tables under fairy lights while chefs cook chargrilled dishes over live charcoal, a rarity in London. The sea bream in olive oil and lemon, garlic-marinated chicken souvlaki and fresh pitta with hummus and tzatziki are the draws. Down the road at Maida Hill Market, butchers and fishmongers share space with an Italian deli and an Asian supermarket – the kind of place where you can buy sumac, belacan, panko and gungo peas in one errand.

Nearby Mosob is one of the city's best Eritrean-Ethiopian restaurants, serving a vegetarian platter of lentils, split beans, peas and cabbage on a metal tray lined with spongy injera flatbread, eaten by hand. For a South Asian fix, Dhaba@49 channels the roadside dhabas of India and Pakistan with truck-art decor, dahi sev puri, vada pav and a signature fried fish and lamb biryani. The Rug Café, in the old Windsor Castle pub where the Rolling Stones and U2 once played, blends Taiwanese, Korean and Japanese influences – including a Japanese noodle dish with ham salad and egg that's hard to find elsewhere in the UK.

Culture runs deep here too. The YAA Centre on Chippenham Mews, Westminster's only officially recognised combined Black arts and community centre, has anchored Notting Hill Carnival preparations since 1986, hosting costume-making and band rehearsals. Joe Strummer of the Clash lived in a squat on Walterton Road. And the strangest sight of all is Gerry's Pompeii: a 50-metre sculpture garden along the Grand Union canal bank, built in secret over 30 years by Irish sculptor Gerry Dalton and only fully revealed after his death in 2019. You can see it from the water on a guided kayak tour costing £40, with private return transfers included.

Why it matters: this is London's diversity without the West End prices or queues – a genuine neighbourhood where a day of eating could span five cuisines and two continents of music history. It suits curious food travellers, canal walkers and anyone who's ticked off central London's obvious spots. Sleep nearby at the Maida Hotel from £117 a night, or the Mason & Fifth Westbourne Park aparthotel from £170, which throws in a pool, gym and canalside restaurant.

Tips: come hungry, use the number 18 bus (London's busiest route, linking Euston and Sudbury) to hop between stops, and book the kayak tour in advance by email. Several addresses – including Tsiakkos – are unmarked or residential-looking, so double-check maps before you set off.
